  • What is SQL?

    SQL, or Structured Query Language, is a domain-specific language used for managing and manipulating relational databases. It is employed for tasks such as querying data, defining and modifying database structures, and controlling access to the stored data.

  • Which are the basic operations in SQL?

    SQL supports several fundamental operations, including SELECT (retrieve data), INSERT (add new data), UPDATE (modify existing data), DELETE (remove data), and CREATE/ALTER/DROP (manage database structure).

  • What is the difference between SQL and MySQL?

    SQL is a language, while MySQL is a relational database management system (RDBMS) that uses SQL. MySQL is one of many database systems that implement the SQL language. Other examples include PostgreSQL, SQLite, and Microsoft SQL Server.

  • Explain the primary key in SQL.

    A primary key in SQL is a unique identifier for a record in a table. It ensures each row has a distinct identity, and it is often used to establish relationships between tables. The primary key constraint enforces the uniqueness and non-null properties of the key.

  • What is normalization in SQL databases?

    Normalization is the process of organizing data in a database to reduce redundancy and dependency. It involves dividing large tables into smaller, more manageable tables and defining relationships between them. Normalization helps maintain data integrity and avoids data anomalies.
